This invention has reference to ventilators especially designed for use in ventilating rooms in such a way as to eliminate any possibility of draft on the persons occupyng the room.

An object of the invention is to provide a ventilator which will direct air upwardly against the ceiling of the room causing a circulation of air to drive the foul air from the room.

Another important object of the inven tion is to provide a ventilator which will have a neat appearance when positioned in the window trim, or when placed in the wall during the construction thereof.

A still further object of the invention is the provision of means for operating the ventilator, the operating means being such as to permit of adjustment of the ventilator to regulate the passage of air into the room.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of What is claimed, without departing from the spirit of the invention.

Referring to the drawings:

Figure 1 is an elevational view showing the ventilator as positioned in a window trim.

Figure 2 is an elevational view illustrating the outer side of the ventilator.

Figure 3 is an enlarged sectional view through the ventilator.

Figure 4 is an enlarged sectional view taken at right angles to Figure 3.

Referring to the drawings in detail, the device includes'a box-like body portion inclicated generally by the reference character 5, the same being formed preferably of sheet metal material having its front and rear sides open. 7

The central portion of the body is braced by means of the partitioning member 6 which is held between the upper and lower walls of the body portion, the rear edge of the par- 1928? Serial No. 275,046.

to the interior of the body portion of the I ventilator. A screening member indicated at 8 is held against the member 7 and acts to screen the air as it enters the body portion of the ventilator. A closure indicated at 9 is hingedly connected to the body portion 5, at 10, the closure being provided with end plates 11 formed with curved openings 12 to accommodate the pins 13 that extend inward- 1y from the end walls of the body portion. It will thus be'seen that these end plates 11 prevent the air from passing through the body portion at points between the ends of the closure 9 and body portion.

The openings 12 are of such lengths that the closure 9 will be restricted in its movement, or

will be prevented from moving to a point. beyond the position as indicated in dotted lines in Figure 4, so that air passing through the ventilator will be directed upwardly against the ceiling of the room ventilated by the device.

Secured to the closure 9 are brackets 14 to which thebolt 15 is connected, the bolt being held in spaced relation with the closure 9, I

by means of the brackets, to provide a clearance for the link or plate 16, which is formed with an enlarged opening to accommodate mounted in the clips 19 that in turn are secured to the window trim. The lower end of the rod 18 extends at right angles defining a handle 20 whereby the rodmay be operated to move the ventilator to open or close the same.

vWhile I have shown and described the ventilator as positioned within a window trim, it

is to be understood that the device may be if? positioned in the Wall of a building during the construction of the Wall.

I claim:

A (ventilator including a swinging closure,

a bolt secured to the closure and held in spaced relation' therewith, an operating rod; a laterally extended portion at the upper end of the rod, terminating in 'an upwardly ex i tendedportion disposed adjacent to the bolt, a connecting link, saidflink having an enlarged opening at one end to accommodate the boltand having an enlarged opening in the opposite end to accommodatethe upstanding end of the operating rod, and said rod adapted to be rotated to move the closure to its openror closed position. r Y

' In testimony that I claim the foregoing a my oWn, I have hereto aflixedmy signature.
